How to Fix Blinking RED LED - Sony Xperia T, TL, TX, V

To be honest with you there is no immediate fix for this it takes up to a week to fix and this method may not work. I fixed my phone twice now doing this and it's been a life saver. It's for peope in a boot loop that does not cease and will not let you enter fastboot or flashmode.
REQUIREMENTS:
*You will need this SEUS
*Drivers for your phone ( use flashtool and go to where the folder is where you installed it and look for 'drivers' and open and install your respective driver software for your device)
*PC Companion (optional)
*USB Cable
*Windows
*Your Device
All download links can be found in the Downloads Section below.
The Instructions;
1. First of all if you are in a boot loop try to hold the power and volume up button until one vibration is felt.
-If you are still in a boot loop (sony logo repeating) try holding it until 3 vibrations are felt
2. Now if this doesn't work then you need to let the phone boot loop until it goes blank and it can no longer continue to boot. Once this happens if you see 2 red LED blinks or 3 RED LED blinks put your phone on charge via mains.
- Make sure that the phone has a SIM card inserted or the phone will not charge after 15 minutes. Then go back to it when you see a green LED or after 1 hour and try to enter flashmode (green LED)
3. Using SEUS (recommended) select your device and install a new fresh firmware and there you'll have your device running.

What went wrong when the phone develops the blinking red led plaque?

Hi.....I've had a similar problem with my Sony Xperia LT30.....3 days ago it froze and shut off by itself. I've tried many,many things to fix the problem but would never turn on,only the red light. Also the same happened when plugged into the computer would only stay red. Tried putting it into flash mode but it would never last long enough to flash the entire stock ROM with Flash Tool. So I took my phone apart and disconnected the battery for about 10 minutes. Put it back on the charger for 12 hours and got Flash Tool ready to flash the entire Rom this time hopefully. Did not have much hope,considering the countless attempts before with no success. But this time it flashed right away by holding down the volume down button and flashed the entire Rom. This is where I'm stuck now....I know I need to hold the power button down while the green lights on to get it out of Flash mode to charge properly, but when I put the phone on my wall charger I get no light for a few seconds than a solid red light than about 5 minutes later the green light comes on,than repeats the process. So I tried holding down the power button when the green light comes on ,but after a few seconds I lose the green light. it just goes blank than about a minute later the red light comes back on? Is it I just need to leave the phone on the charger for another 12 hours or so to recharge the battery,knowing it takes a long time to charge the battery in this state. Thank You for any help anyone can provide.

[Q] Bricked SP

Hi everyone.
My SP doesn't want to turn on anymore for a unknown reason. When plugging it to the pc\charger the red led appears and then disappears. Non of the tips (power + vol. plus, power + vol. minus) doesn't work.
Please, help. If your suggestion will help, I'll pay you.
put it into charger and leave it charging for like 1-2 hours, also remove sim and sd card

How did this happen?? Try this pull out the back panel and press the reset button with a pin and hold the power button and see what happens
Also you may try this install Sony PC companion This will install all the correct drivers for the phone then take usb cord Holding volume Down And Plug it to the phone. If all goes well the led at the bottom should glow green
I had a similar issue and after 4 days of trying all what i could find out in XDA for bricked Xperia phones my SP is back alive.
For me it happened during flashing (with Flashtool 0.9.11) the stock firmware .257 with to less battery power.
Short Info to my phone when it happened
Sony Xperia SP C5303
Kernel: Dooms v01 (i do not think that this was the problem!)
Bootloader: unlocked
Stock firmware from C5302 version .284
System: deodexed and rooted
When i say flashing i did it always with flashtool because PC Companion and SUS did not recognize my phone at all (with locked bootloader).
My SP was behaving as following.
- When i put the wall charger on the phone nothing happened no lights nothing same if plugged in to the computer.
- If i pressed the power button unconnected the LED flashed red 3 times all the time,
after a while nothing happened anymore (which gave me the indication that the battery is completely empty)
- If i pressed the power button continuous during charging (wall/computer) the red light turned on until i released the power button.
When pressing the Power button long enough during i was connected to the computer the green light turned on and i was in flash mode.
But only for maximum 2 min. This was enough to flash all firmware parts except the system.sin (at ~80 % phone disconnected).
And this was the problem my SP stayed dead.
Before someone asks, standard connecting while pressing the volume down for flash mode or volume up for fastboot mode didn't work.
Now i tryed all:
- Left the phone on the wall charger without doing anything -> nothing
- Left the phone on the computer without doing anything -> nothing
- Left the phone on the wall charger/computer while pressing the power button continuous (did it with a tape) -> nothing except that it went in flash mode and red light again all the time
Now my last try (i was reading this in an X10 thread):
I plugged the phone more than 7 hours to the computer while pressing the volume down button continuously (again taped).
Next morning it first looked like that this also did not work.
But as i disconnected the phone from the computer and plugged in again the red light stayed on.
Ok give it a try i thought and i put the phone to my wall charger for 1 hour or so also here the red light was glowing continuous now.
And yeah i could connect the phone to the computer in the normal way volume down than usb and i was in flash mode.
I was now able to flash the complete stock firmware. After again putting the phone to the wall charger for 1 hour the system was booting :victory: .
And now i saw the problem battery charge in status bar showed 1 % but the firmware start up check showed 55 % .
I remember that i did wipe the battery stats in recovery before all that happened.
No idea if this caused the problem.
However i could now charge my phone and it is still alive relocked and on stock.
Hope this helped and good luck.
To prevent other people from this bad situation i tried to remember exactly what caused the drain of the battery to 0%.
Battery was on 25% at start. (I know this was stupid, i was too impatient as dooms v16 and cwm for locked bootloaders were released :silly
1.I started with trying to update my mobile to stock with PC Companion and SUS,
without thinking about that this will not work with unlocked bootloader. -> first battery drain
2. Got stock FTF for .257 (c5303) and wanted to flash it which did not work got errors always.
My SP was connected flashmode on my notebook a long time while i was trying to fix that (reading XDA, driver config etc).
Several times tried to flash without success.
-> drain, drain and more battery drain not thinking about that i started with only 25%.
3. Gave up on my notebook and connected my phone to the Desktop PC (here the config was ok i knew that from flashing before on that computer).
Meanwhile i assume that my battery was already close to completely empty.
As the flash of the FTF (all parts) started my phone turned off and was "dead", i do not remember on which sin it turned off.
The whole time 1. 2. 3. i never booted i always stayed disconnected or in flashmode.
And than the mess began which i posted in my previous post.
So my SP is officially dead. Need to replace to motherboard.

You should keep pressing that button till your phone's screen goes black and vibrates 3 times if it doesn't do that then either the mobo is dead or the button is broken!
well... that's why I kinda hate sony why not do like most makes do (Like iphone, htc, samsung etc just long press the power button to reset the damn thing! It gets really annoying to keep pulling my case and back cover off and then putting a pencil in that tiny hole in public :/)

watch?v=daNue2RsUbY ( video of my phone with the fading logo )
had the same problem with mines ( i manage to record this fading logo part )
hours later after the record my phone won't even turn on and it only shows that red light popping up when i press the power button
i brought it to sony's service center here and they replaced the battery, that managed to fix it <3
For me pressing the back off button and volume + button force it to fastboot mode. From there just flash a kernel and it is fixed.
which kernel???

Dead xperia T

Well my GF had a lot of trouble with this phone, we replaced the battery 3 times due to them failing. Anyway I updated it to official 4.3 for her and left it totally stock, no root or anything. All was well for a few days. One night we left it charging, when we woke up it was still pretty dead. She used it for about 5 mins then it died, now it won't charge or switch on! Got it charging offline but still didn't take any juice. Flashed in flashmode several times, now if I connect to anything it goes straight into flashmode and still won't charge! I bought her a galaxy s2 for now but is there anything we can do? Is it possible it needs yet another new battery?
Just to add I tried all the fixes such as leave it on charge, remove battery, button combo etc. When it does "charge" it doesn't take any charge
Sent while my supervisor wasn't looking
Try replacing the battery again and if this happens again it is definitely a hardware problem

I don't want to start a new thread, so I will post it here. My Xperia T is a dead phone in the moment and I was searching the web and of course xda to find a fix (like for Xperia Z).
How it happened: Yesterday my phone was working like a charm with CM11. I wanted to sell it and so I was trying to flash a stock rom. The flashing aborted with error every single time (Processing system.sin). I was able to flash all the .sin except for system.sin
After the phone was a soft brick I could enter fastboot/flashmode and flash the kernel from CM11 and install it without any problems.
I tried several times to flash stock until my phone bricked. Now it is charging and nothing happens, no fastboot, no flashmode, no sign of life. Only when the battery is detached the LED flashes one time (red) when cable is connected
Edit: The phone was able to go in flashmode but after few seconds it disconnected, in reconnected in flashmode. Also the phone is now recognized by the computer as "qhsusb-dload"
Edit Update: When I connect the phone to the computer an press Vol+ and Power Button for a longer time, the LED turn on (red color) and the qhsusb-dload disappears from device manager. After 2-3 seconds the LED turns of and the device manager shows qhsusb-dload again.
Now I have connected the phone to wall charger with a rubber band on the power button and sometimes the red LED turns on and stays for a few seconds

[Q] Battery dies, no restart, red light in charger

So yesterday my Xperia SP's battery died, I put it in the charger and it restarted but immediatly died again while in the charger (2x)
After that it didn't restart anymore and it only gave me a red light while in the charger (sometimes red light, sometimes no light) also when I push the on-button while not in the charger a red light starts blinking. Also my computer does not recognize the phone when I plug it in.
I read on some forums that more people suffer from this problem and they had the luck to find a solution with a hard reset.
A hard reset does nothing with my phone, I push the button on the back for a minute and nothings happens, I charged it the whole night (with the red light on) and this morning still nothing.
So please is there another solution to this problem without the back reset button? Please help.

Hello.
This may sound repetitive but I will need you to do it. Could you hold the small button under the battery for roughly 40 seconds straight? Afterwards, try to charge it and start it up. If it fails, tell me, I have another method queued up for you!

If you plugged in the charger, the LED is constantly red right? Even after countless hours it still lights up red right?
If so, please give it a nice 2 hours of charge. And then let's get to know how long could your phone survive. THis is to check the battery condition of your XSP.
You'll need Flashtool and a proper drivers installation. Follow these steps:
This should be easy to recover. The prerequisites are a stock ROM ftf and Flashtool
Install flashtool
Move the stock ftf into "firmwares" folder within Flashtool's install directory (default C:\Flashtool\firmwares)
Execute the drivers installer located within "drivers" folder inside Flashtool's install directory (default C:\Flashtool\drivers)
Tick "flashmode drivers", "fastboot drivers" and lastly scroll down a little bit, find "Common drivers for Viskan board" and tick that as well. Finish the installation
Open flashtool. Make sure you ran it as an administrator to avoid conflicts.
Hit the lightning icon
Choose flashmode
Choose the firmware you have downloaded
Under the WIPE section, untick DATA if you want to preserve data
Continue. This is ask you to connect your XSP in flashmode. To do so, make sure your phone is turned off completely, hold volume rocker down and connect it to your computer. Once the LED bar lights green, you may release the volume rocker.
Flashing process will run. It is important not to interrupt the process!
Once complete, remove the cable from your phone and turn it on. You have your phone back.

XSP won't charge or boot

Hi
I am stuck with a phone that won't boot, charge, or be detected by flashtool (or windows) and will not boot in flashmode/fastboot either.
I had plugged in the phone for charging when the battery was considerably low ~ 5-10% before I went to sleep. I remember the red LED glowing, meaning the phone must've been charging.
The next morning I check the phone, the LED was STILL red and the handset was kind of dead - no response at all, whatsoever. Even the reset button on the bacl panel doesn't work (no vibration).
The phone was running BlissPop (5.1.1) with Tangerine kernel.
Now when I plug in the phone for charging, nothing happens at all, not even the red LED. The LED does glow red for as long as I press and hold the power button while it is plugged in (both PC and wall outlet)
I took it to the service center; they say they'll have to change the motherboard. Obviously the phone is not in warranty and there is no way I can pay 10,000 INR that Sony is demanding for the job.
Someone somewhere in the forums suggested allowing the battery to drain completely, but I don't think my battery is holding any charge.
Can anyone help me out?
Thanks

1. Press and hold the reset button for 8 seconds and check if it vibrates. Now plug in charger as there is a possibility that phone is not booting because of insufficient charge.
2. Charge for atleast 20 min without switching on phone.
3. Make sure flashtool is installed properly and so as drivers.
4. Flash Stock ftf
If the above didnt work then try Fastboot mode and simply flash Tangerine kernel.
If nothing works, then its an hardware issue and there is no point in spending 10k in repairing.
Get yourself a brand new Moto G or yureka.
http://forum.xda-developers.com/showthread.php?t=2717303 <- this guy had a pretty similar problem and managed to fix it
I was following the steps he provided: i plugged the phone to PC and held the power button pressed. Surprisingly the PC did recognize the phone after a while- but it was only momentarily and the red LED also stopped glowing. Unfortunately I haven't been able to reproduce a similar situation after that.

I try get into recovery to make my first attempt to get out of this mess when i got into recovery it shows a message can't mount system partition.
and than i restarted it to give it one more try and it goes on again but no success in charging. Touch was working that time next time i try to get into recovery ans during in recovery it's touch goes down and now it become worse. i don't have touch and don't have power on.
